BACKGROUND OF THE INVENTION

1. Technical Field

The present invention is a portable electronic device, and is particularly a portable electronic device having a magnetic element.

2. Related Art

Due to the popularization of mobile networks, the features required by consumers of portable electronic devices are becoming increasingly improved. A light, thin, short, and small notebook computer is commercially available, but since a keyboard module is still of a certain thickness, further reduction of the thickness of the notebook computer is limited.

Since touch technology continues to advance and network browsing and search operations do not of the require the typing of many characters for an extended duration, a tablet computer without a keyboard module has gradually become popular on the market and even has a trend of replacing the conventional notebook computer. However, when many characters must be typed, the tablet computer without a keyboard module still causes inconvenience to a user.

In order to solve the problem that inputting characters in the tablet computer is not quick enough, various tablet computers with a keyboard module externally connected in a wireless or wired manner are commercially available. In this way, when only the network browsing function needs to be executed, an interface of the tablet computer may be used; when many characters must be typed, the interface is combined with the keyboard module.

Currently, when the tablet computer on the market is combined with the keyboard module, the keyboard module enables the tablet computer to stand and incline at an angle, to provide a good angle of view for the user. However, the binding strength of the tablet computer and the keyboard module is often insufficient, resulting in a situation that the tablet computer and the keyboard module are easily separated from each other.

SUMMARY

In view of this, the present invention provides a portable electronic device, including a first case, a movable magnetic part, a second case, and a second fixed magnetic part. The first case has a top plate and a first accommodating space, where the top plate includes a top surface and a first engagement surface, the first engagement surface has at least one first through hole, and the first through hole communicates with the first accommodating space. The movable magnetic part is accommodated in the first accommodating space and is capable of performing motion displacement relative to the first through hole, to be selectively exposed out of the first through hole or refracted into the first through hole. A side of the second case has a second engagement surface corresponding to the first engagement surface, and the second engagement surface is capable of selectively adjoining the first engagement surface or being separated from the first engagement surface. The second fixed magnetic part is disposed at a place of the second engagement surface corresponding to the movable magnetic part, where when the second engagement surface adjoins the first engagement surface, the movable magnetic part is exposed out of the first through hole after being attracted by the second fixed magnetic part and is absorbed to the second fixed magnetic part, so that the second case is positioned on the first case.

Therefore, in the present invention the second fixed magnetic part on the second case attracts the movable magnetic part in the first case, so that the second fixed magnetic part and the movable magnetic part are directly magnetically absorbed together, so as to improve magnetic absorption strength and binding stability between the first case and the second case. In the following, implementation manners of the present invention are further described with embodiments and drawings.

DETAILED DESCRIPTION

FIG. 1 is a three-dimensional view of a specific embodiment of the present invention and FIG. 2 is a schematic partially exploded view of a specific embodiment of the present invention. Please refer to FIG. 1 and FIG. 2, in which a portable electronic device 1 is disclosed. The portable electronic device 1 of this embodiment includes a first case 10, a first fixed magnetic part 13, a movable magnetic part 14, a second case 20, and a second fixed magnetic part 24.

The first case 10 has a bottom plate 11 and a top plate 12 corresponding to each other with an interval from top to down. The top plate 12 preferably has a positioning recess 121 at a proper place. In this embodiment, the positioning recess 121 is a recessed structure with a V-shaped cross section and is formed with a first engagement surface 121 a and a holding surface 121 b opposite to each other. A positioning space is formed between the first engagement surface 121 a and the holding surface 121 b opposite to each other. A predetermined inclined angle is formed between the first engagement surface 121 a and a top surface 122 of the top plate 12. The first engagement surface 121 a has at least one first through hole 12 a at proper places for the movable magnetic part 14 to pass through. An accommodating space 18 is formed at the bottom of the first through hole 12 a.

In another implementation aspect of the present invention, the top plate 12 may also not have the positioning recess 121 but have the first engagement surface 121 a which is even with the top plate 12 and is a local block of the top plate 12. The first engagement surface 121 a also has at least one first through hole 12 a at proper places for the movable magnetic part 14 to pass through. An accommodating space 18 is also formed at the bottom of the first through hole 12 a.

The first fixed magnetic part 13 is fixed at a location of the bottom plate 11 more adjacent to the accommodating space 18 than the first through hole 12 a. Additionally, the first fixed magnetic part 13 may also be fixed at a bottom location of the accommodating space 18. The first fixed magnetic part 13 has an inclined absorption surface 13 a substantially parallel to the first engagement surface 121 a. At least the absorption surface 13 a is of a metal material capable of absorbing a magnet. For example, the whole first fixed magnetic part 13 is a metal block or a magnet capable of absorbing a magnet, or a main body of the first fixed magnetic part 13 is of a plastic or other non-magnetic material, but the absorption surface 13 a is formed by a metal layer or a magnet layer capable of absorbing a magnet. A material of the first fixed magnetic part 13 may be a paramagnetic material, for example, iron, martensitic series stainless steel, or ferrite series stainless steel.

The movable magnetic part 14 is movably disposed in the accommodating space 18, and absorbed to the first fixed magnetic part 13 through a magnetic force, or may also not be nestled to the first fixed magnetic part 13, but attracted by a magnetic attraction force, and an interval is still kept between the movable magnetic part 14 and the first fixed magnetic part 13. The movable magnetic part 14 has a first magnetic attraction end 14 a and a second magnetic attraction end 14 b. The first magnetic attraction end 14 a may be absorbed to the absorption surface 13 a of the first fixed magnetic part 13. When the movable magnetic part 14 is absorbed to the first fixed magnetic part 13, the second magnetic attraction end 14 b does not protrude out of the first through hole 12 a and is substantially even with the first engagement surface 121 a (Please refer to FIG. 8). When the movable magnetic part 14 is separated from the absorption surface 13 a so that the movable magnetic part 14 is capable of moving, the second magnetic attraction end 14 b may protrude out of the first engagement surface 121 a from the first through hole 12 a (Please refer to FIG. 9). In this embodiment, the movable magnetic part 14 is a permanent magnet, for example, a neodymium iron boron magnet.

Please refer to FIG. 1 and FIG. 2, the second case 20 has a second engagement surface 221 a. A bottom of the second case 20 lies against the positioning recess 121 of the first case 10 according to user requirements, to obtain temporal positioning and binding, that is, the second engagement surface 221 a is held to the first engagement surface 121 a in the positioning recess 121. Please refer to FIG. 3, in an implementation aspect, the second case 20 is pivotally connected to a first pivotal connector 19 of the first case 10 through a support plate 30, so that the second case 20 can rotate relative to the first case 10. Specifically, a back surface 20 b or other side surfaces other than a display surface 20 a of the second case 20 has a second pivotal connector 29, so two ends of the support plate 30 are pivotally connected to the first pivotal connector 19 of the first case 10 and the second pivotal connector 29 of the second case 20, so that the first case 10 and the second case 20 are bound pivotally. In this case, the second engagement surface 221 a at the bottom side of the second case 20 is in a free motion state relative to the top surface of the first case 10, so the second engagement surface 221 a can be in contact with the top surface 122 (for example, located in the positioning recess 121), or leave the top surface 122. However, a relative relationship between the first case 10 and the second case 20 is not limited thereto. At least one binding device (not shown), may be disposed in or near the positioning recess 121 of the first case 10, so that if required, the bottom side of the second case 20 is inserted into the binding device to be fixed, and is combined with the first case 10 for use.

Please refer to FIG. 4, in which the second fixed magnetic part 24 is fixed in the second engagement surface 221 a of the second case 20 of the portable electronic device 1 of this embodiment. A specific manner of fixing the second fixed magnetic part 24 may be disposing two corresponding snap parts 27 on the second engagement surface 221 a. The two snap parts 27 are of an L shape and are disposed at an inner side of the second engagement surface 221 a. An interval is formed between the two snap parts 27 to form an accommodating space 27 a. The second fixed magnetic part 24 is fixedly accommodated in the accommodating space 27 a between the two snap parts 27. Additionally, the second engagement surface 221 a has a second through hole 22 a communicating with the accommodating space 27 a. When the second fixed magnetic part 24 is accommodated in the accommodating space 27 a and is fixed, a part of the second fixed magnetic part 24 is exposed out of the second through hole 22 a.

Please refer to FIG. 5, FIG. 6, and FIG. 7, in which the portable electronic device 1 further includes a limiting part 16, having an accommodating hole 16 a with a shape matching the movable magnetic part 14 and used to sleeve the movable magnetic part 14, so that the accommodating hole 16 a and the movable magnetic part 14 are bound together and can be movably disposed in the accommodating space 18. Additionally, the limiting part 16 has a flange 161. A width of the flange 161 is greater than a caliber of the first through hole 12 a, so when the second case 20 and the first case 10 move to be separated from each other so that the second engagement surface 221 a is separated from the first engagement surface 121 a, the second fixed magnetic part 24 pulls the movable magnetic part 14. In this case, the movable magnetic part 14 and the limiting part 16 may be limited by the first through hole 12 a with a smaller caliber through the flange 161 and do not be pulled out of the first case 10 (please refer to FIG. 9).

To continue this description, in an implementation aspect the movable magnetic part 14 is of a trapezoid block shape, that is, an area of the first magnetic attraction end 14 a is greater than an area of the second magnetic attraction end 14 b, so the accommodating hole 16 a of the limiting part 16 is also formed with a trapezoid space, so as to ensure that the movable magnetic part 14 is not removed from the limiting part 16.

To continue the above, Please refer to FIG. 2, FIG. 6, and FIG. 7, in which in an implementation aspect, a guide post 131 is disposed at each of two sides of the first through hole 12 a at the bottom side of the first engagement surface 121 a, and the two guide posts 131 are parallel to each other; each of two sides of the flange 161 of the limiting part 16 is provided with a guide hole 161 a. In this way, the guide post 131 passes through the guide hole 161 a, so that motion of the limiting part 16 and the movable magnetic part 14 is smoother through guide of the guide post 131.

Please refer to FIG. 8 and FIG. 9, in which when the second case 20 moves on the top surface 122 of the first case 10 and falls in the positioning recess 121, that is, when the second engagement surface 221 a is closed to the first engagement surface 121 a, the first magnetic attraction end 14 a is separated from the first fixed magnetic part 13 after being attracted by the second fixed magnetic part 24 (for example, in the case that a magnetic attraction force of the second fixed magnetic part 24 is greater than that of the first fixed magnetic part 13), where the first magnetic attraction end 14 a is originally absorbed to the movable magnetic part 14 of the first fixed magnetic part 13. The attracted movable magnetic part 14 passes through the first through hole 12 a of the first engagement surface 121 a and protrudes out of the first engagement surface 121 a, and then passes through the second through hole 22 a of the second engagement surface 221 a (however, the movable magnetic part 14 may certainly also be designed not to pass through the second through hole 22 a), and then the second magnetic attraction end 14 b is absorbed to the second fixed magnetic part 24. Since the movable magnetic part 14 passes through the second engagement surface 221 a of the second case 20 and is absorbed to the second fixed magnetic part 24, separation resistance between the first case 10 and the second case 20 is increased, and binding stability of the first case 10 and the second case 20 is improved. When the second engagement surface 221 a is separated from the first engagement surface 121 a, since the attraction of the second fixed magnetic part 24 is lost, the movable magnetic part 14 is immediately re-absorbed to the first fixed magnetic part 13, and therefore, the second magnetic attraction end 14 b is retracted into the first through hole 12 a and is substantially even with the first engagement surface 121 a.

The foregoing embodiment of the portable electronic device of the present invention may be applied to the field of tablet computers, that is, the first case 10 may be a case of a keyboard expansion base, and the second case 20 is a case of a tablet computer. However, the embodiment may also be applied to the field of notebook computers. For example, the first case 10 may be a case of a host base, and the second case 20 is a case of a display screen. No matter which field the application implementation is in, the user can move the bottom of the tablet computer/display screen back and forth relative to the keyboard expansion base/host base, so as to adjust a view angle of the display surface. In this case, preferably, when the user moves the bottom of the tablet computer/display screen to the positioning recess 121 in a sliding manner, to complete initial positioning, and then the movable magnetic part 14 attracts the first fixed magnetic part 13 so that stable positioning can be further kept. When the tablet computer/display screen is intended to be separated, the user only needs to slightly apply a reverse force on the tablet computer/display screen, to overcome the magnetic attraction force to be separated from the keyboard expansion base/host base.

It is worth mentioning that, since for any two elements bound by attraction of a magnetic force, exchange of the locations of the two elements still does not affect the magnetic attraction effect and is considered as an equivalent action. Therefore, based on the description of the foregoing embodiment, another implementation aspect may be derived. Specifically, the second fixed magnetic part 24 may be disposed at the first engagement surface 121 a of the first case 10; correspondingly, the first fixed magnetic part 13 is disposed in the second case 20, and the first fixed magnetic part 13 and the second engagement surface 221 a form an accommodating space; the movable magnetic part 14 is disposed and moves in the accommodating space formed by the first fixed magnetic part 13 and the second engagement surface 221 a. Like the foregoing implementation aspect, this implementation aspect may also achieve the efficacy of increasing separation resistance between the first case 10 and the second case 20 and improving binding stability of the first case 10 and the second case 20.

It is also worth mentioning that, for any two elements bound by attraction of a magnetic force, it is possible that the two elements are both magnets capable of generating active magnetic attraction, and it is also possible that one of the two elements can generate active magnetic attraction and the other one is magnetic attractable metal capable of being passively magnetically attracted and containing, for example, iron. Therefore, in the foregoing implementation aspect, the first fixed magnetic part 13, the movable magnetic part 14, and the second fixed magnetic part 24 all belong to the concept range, that is to say, when the movable magnetic part 14 is a magnet for generating active magnetic attraction, the first fixed magnetic part 13 and the second fixed magnetic part 24 may also be magnets for generating active magnetic attraction or may be magnetic attractable metal capable of being passively magnetically attracted; on the contrary, when the movable magnetic part 14 is magnetic attractable metal capable of being passively magnetically attracted, the first fixed magnetic part 13 and the second fixed magnetic part 24 are magnets for generating active magnetic attraction.

In another embodiment, the first case 10 may not be disposed with the first fixed magnetic part 13, that is, when the second case 20 is separated from the first case 10, after the moving magnetic part 14 is separated from the second fixed magnetic part 24 due to blocking of the flange 161, the moving magnetic part 14 drops down according to its gravity, the state that the moving magnetic part 14 is retracted into the first through hole 12 a and the first engagement surface 121 a is kept smooth may also be reached.

Additionally, in design a certain margin may be left between the guide post 131 of the first engagement surface 121 a and the guide hole 161 a of the limiting part 16, so that the whole combined structure of the movable magnetic part 14 and the limiting part 16 retains certain lateral motion elasticity when performing axial displacement motion in the first through hole 12 a of the first engagement surface 121 a, so that the second magnetic attraction end 14 b may have sufficiently large elasticity to finely regulate an angle to be completely nestled and absorbed to the second fixed magnetic part 24.

Furthermore, the terms “fixed” and “movable” used in the first fixed magnetic part 13, the movable magnetic part 14, and the second fixed magnetic part 24 in the foregoing embodiments are relative concept words other than absolute concept words, that is, the first fixed magnetic part 13 and the second fixed magnetic part 14 are not limited to be completely fixed, and in fact, the first fixed magnetic part 13 and the second fixed magnetic part 14 are allowed to move slightly or move in a limited narrow range.
